Fig. 3

The relationship between PET and CMR for regional myocardial perfusion (rest and stress included, a). The dashed line represents the line of regression. The solid line indicates the line of identity. b Bland-Altman plots for the difference between PET and CMR for regional MP. The solid line represents the mean difference between the two methods. The dashed lines indicate +2SD and -2SD, respectively. There is significant correlation and small bias between PET and CMR for assessing regional MP in 16 of the 17 segments of the left ventricle. CMR = cardiovascular magnetic resonance, MP = myocardial perfusion, PET = positron emission tomography
